WINDOW {coirsrnuc'rion l Be it known that I, J Us'rus' Jnssn SMITH, a citizen of the United States, residing at New York, in the county of'New York and State of New York, have V invented certain p new and useful Improvements'in Window'E Construction; and I do hereby declare the y following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which' it a-ppertains to make and use the same. i y Mypresent invention relates to 'improve- 'nentsi'n window construction and' it con, sists inprovidin av metallic sash frame and i 'window frame w ich is lire-proof, compact,

, substantially-airtight in the joints, simple.

andjcheap in construction, easily assembled,

and efficient in operation.

r lMy invention will be understood by reference to the accompanying drawings, in I `which the same parts are indicated by the the other side of the window', when, if the same letters throughout the several views.

Figure l shows the'interior of a window lookigjout; parts' being' broken aw'ay. Fig. 2j;shw's ha*v section along thel line 2 2 ofj Figflon'a' larger scale, and. looking down.; 3 shows ,a section along the line 3 3, of ig. 1, and looking in the direction of the arrows. Fig. Ltis a similar viewto Fig. 2, butshows a sectionthrough the weight box' 'just'.'abovefthepulleys; Fig. 5 is a detail` showing 'the accordlon spring plate used as a combined spring and weather strip in the window frame,-` and Fig. 6 shows in cross section a modied form of sash gen4 erallysimilarto that shown in Fig. 2.

A.4 re esentsa masonryorconcrete wall, in whic the weight box A0 is formed. 'The side of this weight box is closed by a plate B, bent inward to form tw'o guide grooves B0 for'the sash, which grooves are preferably separatedby the bent vchannel rib or parting railY B', formed in said plate, as shown'in Fig. 2. A,' lhis plate B is attached to; the .masonry A by screws C andsockets C', which sockets are preferably embedded in said masonry when the skeleton frames are in place and the masonry is constructed. Above thesashesa similar .plate B is provided with a singlev guide groove B0, as shown in Fig. 3. The panes D and D are, held in a sash, comprising the side rails E ,and/the top rail E. The side rails are pref# rablyl composed ofhtwo plates detachably I Specication of'Letters Patent. :Application mea December a1, 1909. serial N9. 534,351.

connected together as shown in Fig. 2, in which the plate e is hooked over as at c' to engage the rib e2 of the opposite plate, which is recessed as at e and is bent on itself as at e4, the inner ends el5 engaging strips of rubber, or other suitable material. The two plates may be connected together by any suitable clamps, such as F, which consist of screws f connected by spring washl ers f2 to rivets f, or' instead of this arrangement a simple rivet such as 1F', shown in Fig. 6, may be adopted. Accordion spring plates H are riveted'as at H0 in the side and top grooves of the window frame, and bear on their inner edges against the surface e3 of the sash, as shown in Fig. 2.

To assemble the sash in the window frame, it will only be necessary to press the sash against this spring plate H, compressing same until the opposite side ofthe sash can be swung into the corresponding groove on sash be released, the resiliency of the two springs will center the sash and the said spring plates will serve not only to steady the sash'in'the 4windev/ fra-me, but will also serve as weather-strips to prevent drafts of air rfrom passing -around the' edges of thefs'ash, between it and the window' frame.

By using such resilient plates the necessity for a snug fit is obviated,` and a self fitting sash is secured, thus insuring a great saving in workmanship. By having the sides of the sash recessed, a wider spring plate ma be used, and a larger opening securec. These accordion spring plates are shown in detail in Fig. 5, where h represents lthe' corrugations and 71, represent theriv'et holes.

At the top of the window, the sash should preferably be fiat, as at e5, to prevent the accumulation of dust,` which would occur if it were recessed as shown at 4c3 Vin Fig. 2. In this case, the accordion spring H need not have as much resiliency as at the sides of the windows, since it will only operate when the sash is in the closed position and has no function in centering the sash in the window frame; but it provides a tight joint both at the window head and the meeting rails without necessitating exact workmanship. Itis very diilicult and 'expensive to make snug fits in lightmetal constructions. Mounted at the head of the weight box are the pulleys K,Iover which pass the chains I, connected to the weights W. These pulleys are preferably set at an angle, so that the weights may not interfere with each other in passing, and thus a narrower sash may be used with standard size weights.

lt will be noted that I provide a tire-proof window construction, in which the sash does not project materially from the window jamb ofmasonry, thus enabling a pane of almost the full size of the masonry opening to be used, thus greatly increasing the light admitted, and in which the panes may be readily assembled in the sash and the sashes may be readily assembled in the window frames without the necessity for close Workmanship, in which the springs will prevent rattling, and the accordion plates will o bviate the necessity for weather-strips. It will also be seen that I provide a single bent plate which serves both to close the outer side of the weight box, and to provide guide grooves and a partition rail for the sashes, that the face of this plate projects into the window opening only the thickness of the plate itself and the sides of the sashes project intothe inwardly extending grooves in said plates, thus increasing the light area in the Window opening. The Weight box is preferably molded in the masonry and requires no metal lining. The construction is extremely simple, compact, cheap and e'ective for the purposes stated.

It will be obvious that various modifications might be made in the herein described structure which could be used Without departing from the spirit of my invention.

Having thus described my invention, what I` claim and desire to secure by Letters Patent of the United States is:

1. A lire proof window construction comprisinga weight box, a plate closing one side of said weight box, and bent to form grooves projecting into said weight box, an accordion spring plate mounted in each of said grooves, and sashes projecting into said grooves and normally compressing said accordion spring plates, substantially as described.

2. A fire proof window construction comprising a weight box, a plate closing one side of said weight box and bent to form grooves projecting into said weight box, an accordion spring plate secured in each -of said grooves, and sashes projecting into said grooves and themselves provided with grooves, normally engaging and compressing said accordion spring plates, substantially as described.

3. A flreproof window construction comprising a weight box, a plate closing one side of said Weight box, and bent to form grooves projecting into said Weight box, an

accordion spring plate secured in each oiA said grooves, sashes projecting into said grooves and themselves provided lwith grooves normally engaging and compresslng said accordion sp1-ing plates, pulleys set at a divergent angle above the sides of said sashes, chains secured to said sashes and passing over said pulleys, and Weights saspended from said chains, and passing clear of each other in said weight boxes, substantially as described.

4. A fire proof window construction comprising a weight box, a plate closing one side of said weight box and bent-to form grooves project-ing into said weight box, an accordion sprin plate mounted lin each of said grooves, an sashes projecting into said grooves and normally compressing said accordlon spring plates, pul eys set at a divergent angle above the sides of said sashes,

chains secured to said sashes and passing over said pulleys, and weights ysuspended from said chains, and passing clear of each said grooves, and sashes projecting into said grooves and normally compressing said accordion spring plates, said sashes comprising two interlocking metal plates projecting at one side into said grooves and at the other side gripping the pane, with means for clamping said plates together, substantially as described. f

6. A sash rail comprising two resilient interlocking metal plates, adapted to project into the groove at one side, and to grip the pane at the other, with means for clamping said plates together, comprising a resilient washer fastened to one plate, and a screw passing through the other plate and connected to said Washer, substantially as described.

7. The combination with a window sash and a window frame, of a resilient plate corrugated in V-shaped folds extending transversely of the sash to 'form a spring held edgewise between the sash and the Window frame, and serving both as a yielding centering device for the sash, and as a weather strip Ito prevent the passage of air,

substantially as and for the purposes de-l passage of air7 substantially as and for the purposes described.

9. The combination with a Window frame and sash, of a resilient plate bent t0 form :1n accordion spring, said plate being held edge- Wise between the sash and the Window frame, and serving both as a centering device for the sash7 and as a Weather strip to prevent the passage of air, substantially as and for the purposes described;
